sPRAYER FOR DEHYDRATING APPARATUS I Filed JuneO, 1945 Patented ct. 1948 T OFFICE i SPRAYER FOR DEHYDRATING APPARATUS' Stella A. Kloda, Chicago, Ill. Y Application June 30, 1945, Serial No. 602,524 g The present invention relates to dehydrating apparatus and has for its main object the provision of an improved spraying head or atomizer into which liquid may be fed and from which it may be atomized or sprayed by a centrifugal force exerted thereon by the atomizer.

A still further object of the present invention is the provision of an atomizer of an improved construction having comparatively few parts which may be readily assembled or disassembled.

A still further object of the present invention is the provision of an atomizer consisting of a tray and a closure therefor with means for maintaining the two in a rigid operative position, and wherein the closure may be disengaged for providing access into the tray for removing therefrom solid matter which may accumulate therein.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described and illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views:

Fig. 1 is a side elevational View of the atomizer with a motor connecting therewith for rotating the atomizer and thereby ejecting the liquid therefrom by centrifugal force;

Fig. 2 is an enlarged cross-sectional view centrally through the atomizer and on a vertical plane; and

Fig. 3 is a fragmentary, top plan view of the atomizer, partly in section, taken along line 3-3 of Fig. 2.

Referring in detail to the present drawing there is shown an atomizer having a tray including a circular bottom plate I and an integrally formed annular flange II upwardly projecting from said plate IIl and along its marginal edge. Said flange II is comparatively thicker than said plate I 0. A plurality of closely spaced minute openings or perforations I2 are made in said iiange II and adjacent the upper face of said plate I0, and in a radial juxta-position in relation with the latter.

Cooperating with said tray is a circular closure I3, the marginal portion of which is recessed to eiect a reduced rim I4, which, in the operative position of said closure I3 upon said tray, rests upon the top end of said iiange II, and by virtue of which arrangement the body portion oi said closure I3 enters into said flange II, asis clearly seen in Fig. 2, thereby providing a hermetical seal betweensaid tray and said closure y I3. A rplurality of screws I5 passing through rimV I4 and rigidly engaging iiange II, and between periorations I2, provide locking means between said tray and said closure I3. I

From the hereinabove description it willfbe seen that said tray' and said closure I3 provide a comparatively shallowgchamber IiiV into which liquidis fed preparatory to its ejection by the centrifugal force through said l Integrally formed lwith said plate I0, and centrally therewith, is a downwardly depending boss Il, which, at its lower end is provided with A a central bore I8, 'into which the free end of shaft I9 is receivable. Thumb screw 20 passing through `the wall of said boss I'I engagessaid shaft I9 and keys the same to said boss II. Shaft I9 connects with, and is driven by an electric motor 2I.

Integrally formed with said closure I3 and centrally thereof, is projection 22 upwardly extending from said closure I3. Said projection is provided with a central orifice 23, the lower portion of which is downwardly aring for defining a conical bore 24. Receivable within said orice 23 is pipe 25 loosely positioned in said orice 23, and maintained in an operative position with projection 22 by collar 26 resting upon the upper end of said projection 22. Connecting with said pipe 25 is conduit 2l connecting by its other end with receptacle 28 in which liquid to be dehydrated is stored. Said receptacle 28 is disposed above the atomizer so that liquid feeds thereinto by virtue of gravity.

When rotary movement is imparted to the atomizer by means of shaft I 9, liquid fed from receptacle 28 through conduit 2'I and pipe 25 and into chamber I6 is forced, due to the centrifugal force exerted thereon by virtue of the rotation of the atomizer, to pass outwardly therefrom through apertures I2 in minute sprays or mist to be acted upon either by cold or hot air and vacuum or by various other known means for the purpose of extracting therefrom water and moisture and thus for dehydrating the same.

It is observed that pipe 25 being loosely positioned within projection 22 is stationary during the rotary movement of the atomizer. No liquid will pass through the space between the adjacent body portion of said projection 22 and said pipe 25 due to the constant suction that is exerted upon the liquid in conduit 21 and pipe 25 engendered by the perforationsY I2.

ed therein and which was incapable of passing1 through apertures I2.

While there is described hereina preferred bodiment of the present invention, it is vnever--` g theless to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed,`

What l olairn as new is: Ana-pparatus Yfor dehydrating liquids comprising a tra'y'having an annular upstanding flange with -circumferentially disposed openings therethrough andv integrally formed on the outer vperiphery of said tray, a closure for said tray seated' upon said-ange and' cooperating with the tray to-form abhamber in opencommunication with the' openings in said flange, a shoulder'on the 'lperipheryo the closure abutting the inside of said `flange, means to detachably aiiix the closuieft "said iiangegnany upstanding lprojection formed integral with said closure having an annular central opening therein, said opening terminating in an inverted cone in open communication with the chamber, a pipe slidably inserted into the annular central opening in the upstanding projection, a collar formed on said annular pipe adapted'to rest on the upstanding projection, said pipe terminating substantially at the base of the inverted cone and being adapted to.. remain; stationary. while the Yc ,ovler rotates and to bereniovably insertedintofthe,annular central opening of the upstanding projection, and means to rotate the tray and cover independently from the pipe and collar for discharging lii'id'frornthe tray by centrifugal force.
